WARNING
Vulkan may be incompatible with some mods, and your system if its older then the year 2016. If you want great performance but more compatible, use our Sodium version!

Send me a message on the Discord support "https://discord.gg/BggfhEXNVW" for any questions, help with the Modpack, or recommendations, and I am always happy to listen.

If you want to send me a message/report for a glitch/crash, please send it to "https://discord.gg/9Exk4BMjnr", I would love to see messages/reports so I can fix the problem and give you a better experience from NanoFabric

Concerns that may occure

  1. Will it kill the vanilla feel?
    No, NanoFabric was made to make the vanilla Minecraft intact and will NOT remove the vanilla feel but instead, just performance to make it feel smoother.
  2. Will it work with other mods?
    No and Yes. Vulkan verions in my Modpack could cause crashes or glitches because Vulkan could be the main reason, as it changes the API from OpenGL to Vulkan, while with Sodium was made to give great performance and better compability with other mods by not including Vulkan.
  3. Will this improve FPS massively?
    Yes, NanoFabric is focused on massively improving performance, from doing stability increase to FPS increase. For Low to High end PC's users to enjoy.
  4. Will this break Multiplayer servers?
    No, neither Vulkan and Sodium most likely would not break your multiplayer servers, but Vulkan does have a higher chance of breaking servers but it's rare to none.
  5. Is this safe to use?
    Yes, all of these mods was tested and reviewed to see if its safe or not, if they weren't safe, then they would be removed and will never be added to NanoFabric even if they claimed that they stopped, they already broke our trust.
  6. Do I need to configure anything?
    No, it was made to be ready out of the box, but you can change it in your needs for performance.
  7. Will it update to the newest version?
    Yes, I'll try and make NanoFabric update to the newest version of Minecraft for you to play.
  8. Can I remove or swap mods inside NanoFabric?
    Absolutely, you may add/remove any mods you want in NanoFabric, from what you want and need for your Minecraft worlds but if you remove/swap some performance mod it may decrease your FPS.
  9. Will this change gameplay or add new features?
    No, this is just a performance mod that will not add ANY new mechanics or items in Minecraft, for you to enjoy the performance and game play the vanilla Minecraft.

Shader & Resource Pack Recommendations (1.21.5+) These are all my suggestions to make Minecraft look and feel better. All are tested, reviewed, and compatible with version 1.21.5 and up.

Shader recommendations

  • For Low End PC Users
  1. Mellow Shader, gives the best performance and stability while giving good visuals, and will be up to date on every Minecraft versions for you to enjoy.
  2. MakeUp-UltraFast, gives good performance and stability while giving better visuals but with worse performance as the downside, but will be in every Minecraft version.
  • For High End PC Users
  1. Complementary Shaders - Reimagined, adds massive amounts of detail like glowing effects on blocks and entities and adding advanced lighting detail.
  2. BSL Shaders, same as Complementary Shaders - Reimagined but with less details but still very aesthetic to look at.
  3. IterationT, amazing shader with good details, amazing looks and mid performance. This is not recommeneded for low end pc as this will kill your FPS.

ResourcePack recommendations

  • For Better Animations
  1. Fresh Animation, adds more unique and better animations for every Mob, making the experience better.
    ^-- Fresh Animations - Extensions, adds more details for Fresh Animation like Creeper edits, more details in pigs, chickens, cows and many more that I can not explain to not waste your time.
  2. Detailed Animations, like Fresh Animation it makes animation look better, but this time its not the Mobs, this time its the players-you, adding many animations to make your avatar not feel stiff nor lifeless.
  • For Better Looks
  1. Bare Bones, it makes blocks and items more simple and a recreation from the Minecraft Trailers but yet... making it still enjoyable.
  2. Motschen's Better Leaves, makes leaves look better and nicer to look at, making a forest look actually natural than flat.
  3. (Bee's) Fancy Crops, it makes crops look better and more full of life.
  4. Dramatic Skys, makes the sky look better as it changes the Vanilla skybox from Minecraft to a prettier one and more realistic.
  5. Story Mode Clouds, makes the clouds look like from Minecraft: Story Mode and still keeps it looking vanilla.
  6. Re-Shaded, makes the world look like it has shader on but in reality it doesn't and without loosing FPS, sadly this doesn't work with Sodium, VulkanMod nor Graphene, but instead just full vanilla rendering.
  7. Fast Better Grass, makes Grass looks simplier but still has that Vanilla feel in it.
  • For PVP
  1. CPVP Essentials ( Crystal PvP ), makes food smaller, no particles and lowers shields to help you in PVP
  2. PvP Swords, makes swords smaller for you to see more than the sword blocking more of your view.

if something breaks or changes, lemme know and I’ll update it
